Edited: This is the finished result and posting.
I know this is going to sound like one of those word problems from my high school algebra text book, but it boils down to this: I need to build a pyramid-shaped urn.
My patron raises Saluki dogs and has them cremated when they die. She wants to put the ashes into an urn shaped like the Great Pyramid of Egypt. She doesn’t want to mix the ashes together and wants to put ashes of 4 dogs in each pyramid. The Great Pyramid has 4 sides of 440 cubits each and is 280 cubits tall in the center. I won’t drag you through all the math of proportions and volume.
I need a pyramid that is 18 inches on each of four sides and 11 1/2 inches tall in the center. At that size, the sides will need to be made of 1/2 inch veneered plywood.
I thought I’d start the frame with two crossing triangles 25.45 long at the base and 11 1/2 tall in the center. That would give me the 4 compartments and the support I need for the edges of the 4 sides.
Have any of you built something like this? Do you have any hints?
